SU376312A1 - DEVICE FOR CONTROL OF THE ACCURACY OF MUTUAL 5 AND 6 LAYOUT OF THE TRAVELING WHEELS OF BRIDGES ^ "- ^^ - Google Patents

Description

one

The invention relates to the control of the accuracy of the relative position of the traveling wheels of cranes during installation and arbitration checks.

The known device for controlling the accuracy of mounting the traveling wheels of cranes contains two bearing elements and a measuring device. Each of the carriers contains a tanga with a groove for the string to be pulled. The measuring device includes an electromagnetic bracket with (Scale, micrometer screw, warning light and measuring angle.

In the known device, the bearing elements and the measuring device are installed. They are poured at the ends of the wheels separately, which increases the time for their installation. To use this device, it is necessary to have a source of electricity at the monitoring site. The use of an electric lock to determine the moment of contact of the square bracket and the string due to the possibility of the presence of knots on the scab can affect the accuracy of control.

The purpose of iC is to increase the accuracy of control and convenience during operation of measuring devices mounted on supporting elements, each of which contains at least one swivel arm with a level and an indicator.

FIG. 1 shows a device, side view; on / fig. 2 is the same, view along arrow A in FIG. one; in fig. 3 - the same, view along arrow B on fit. one.

The device has two bearing elements / with magnets 2. A rod 3 is fixed to each bearing echment, carrying a swivel bracket 4 with a level 5 and an indicator 6. The swivel bracket 4 can rotate around axis 7 with (Rotation of the secret 5. At equal distances from the rods 5 on the supporting elements / supports 9 are attached, each of which has a micrometric head W and an ocular 11. In the field of view of the latter there is a weave of the micrometric head 10 and a string 12, which lies in the prismatic grooves 13 on the shafts 3. At one end string 12 is connected drum 14, and the other - with a cargo of 15.

The device is configured so that the distances from the axes of symmetry of the prismatic grooves 13 on the bar 5 and from the measuring flux of the micrometer heads 10 to the planes of the bearing elements / in contact with the ends of the driving wheels are equal to each other, and with the same level readings 5 the indicators 6 also have the same readings.

In determining the accuracy (relative positioning of the traveling wheels, the carriers 1 are fastened with the help of magnets 2 to the ends

travel wheels. By swinging each of the pivot brackets 4 on the rods, the same indications of levels 5 are achieved. And the readings are taken from the indicators 6. The indications of indicators indicate the deviations from the perpendicularity of the end plane of each running wheel to the plane passing through the upper surface of the rails.

Observations in the oculars //, 12 micrometric heads / are removed from the generator of the string, removed from the H; their readings and determine the magnitude of the wheels turning, with ego to increase the accuracy of control it is necessary to take into account the deviations of the end planes of the wheels to the plane passing through the top surface of the rails.

Subject invention

A device for controlling the accuracy of the relative positioning of the traveling wheels, mainly bridge cranes, containing bearing elements fixed on the extreme wheels with rods for tensioning the string, interacting with measuring devices, characterized in that, in order to increase control accuracy and ease of operation, measuring devices are mounted on bearing elements, each of which contains at least one swivel bracket with level and indicator.
